# ActiveSupport's String methods become bottlenecks once:
#
# - HTTP responses are cached in Memcached
# - JSON documents are dumped to Redis
# - Redis is pipelined
# - Validation is skipped
# - The runner is quiet
#
# With these optimizations, in sample scripts, garbage collection and gem
# requiring take up two-thirds of the running time.
